Who we areIWS is the only Saudi NACE-qualified provider of casing and casing-head welding — an engineering-led company built to deliver documented, code-compliant welds on every well. This is who we are, how we work, and who we work for.
Integrated Wellhead Services is the only Saudi NACE-qualified provider of casing and casing-head welding, serving oil and gas operators including a major operator and major service providers. Our methodology was developed and qualified together with a major operator's technical organization specifically to meet sour-service requirements — and it passed every qualifying test.
Now operating through our registered Saudi subsidiary, IWS treats every job — from installation through code-compliant welding, post-weld heat treatment and gas testing — as auditable engineering. The result is consistent, crack-free welds, a documented temperature record for every weld, and a safety record we hold to without exception.
To provide safe, reliable and high-quality specialist welding services — including wellhead installation, workover, repair and fabrication — ensuring pressure-control integrity and operational efficiency for our oil & gas partners through experienced technicians and qualified, code-compliant procedures.
To be the oil and gas industry's preferred service provider in specialised welding, recognized for our commitment to zero-incident safety, unmatched technical expertise and industry standards.
An IWS crew is trained, certified and accountable — the same qualified people and procedures behind every weld, on every well.
The conventional "old method" of casing-head welding doesn't measure temperature, isn't code-approved, and can't be audited after the fact. The IWS methodology was built to close every one of those gaps.
A chart recorder monitors and documents metal temperatures throughout welding — transparent, precise, traceable preheat and inter-pass records.
Endorsed by recognized international standards — ASME, API and ISO — rather than relying on unapproved field practice.
The same technology is widely and successfully applied to pressure vessels, piping, tanks and pipelines.
A preheat chart is produced for each weld, making adherence to approved procedures simple to verify.
Precise preheat and inter-pass control substantially reduces cracking risk in AISI 4130 material, where inconsistent temperature is a real risk.
No black carbon soot inside the casing head means no contamination and no post-weld cleaning. Localized heating cuts the ~2-hour cooling wait, so testing can start earlier, subject to the approved procedure and client acceptance criteria.
Each procedure is individually qualified for a specific weld and material combination — supported by a Procedure Qualification Record and proven against ASME Section IX and NACE through bend, macro, hardness and tensile testing.
IWS delivers for a major operator and for the leading service providers in the industry.
